EB3A Surrounding Space Question

How much space should I provide surrounding my entire EB3A unit? I am building a wooden placeholder for it in our camping rig and I would like to know how much space to make room for. I can’t find this info anywhere. Thanks in advance!

@DuckFin90 The following is the dimension diagram for EB3A. Please allow 30cm of space for heat dissipation based on this.
